If a woman experiences spots of blood
during the day in the month of Ramadan and
these spots last throughout the month while
she is fasting, would her fasting be valid?

Answer

All perfect praise be to Allah, The Lord of the
Worlds. I testify that there is none worthy of
worship except Allah, and that Muhammad,
sallallaahu 'alyhi wa sallam, is His slave and
Messenger.
Shaykh Ibn ‘Uthaymeen said: "Yes, her
fasting is valid and these spots are not
considered as significant as they are merely
from the veins. It was narrated that ‘Ali ibn
Abi Taalib, may Allah be pleased with him,
said that such spots of blood that are like a
nose-bleed, are not menstruation."
